实现效果：
知识运用：
File类的Create方法 //在指定路径中创建文件
public static FileStream Create (string Path)
File类的Delete方法 //删除指定文件 不存在则引发异常
public static FileStream Delete (string Path)
实现代码：
private void button1_Click(object sender, EventArgs e)
{
SaveFileDialog P_SaveFileDialog = new SaveFileDialog();
if (P_SaveFileDialog.ShowDialog() == DialogResult.OK)
{
File.Create(P_SaveFileDialog.FileName);
}
}
private void button2_Click(object sender, EventArgs e)
{
OpenFileDialog P_OpenFileDialog = new OpenFileDialog();
if (P_OpenFileDialog.ShowDialog() == DialogResult.OK)
{
File.Delete(P_OpenFileDialog.FileName);
}
}
